1. x=1  5x=4+x 4x=4 x=1 2. x=3/4 or 0.75 2/3x=1/2 2x=1 1/2 x=3/4 3. x=1 3x-2x+4=15/3 x+4=15/3 x=1 4. x=5 4x+7=2x+17 2x+7=17 2x=10 x=5 5. x=20 .5x=10 x=20

1.  5(x) - [4 + x] = ?        4(x - 1)        4 = ?           x - 1 = ?             Now let's add ( + ) to your sides                         Answer: x = 1  2.  [latex] \frac{2}{3} (x) - \frac{1}{2} [/latex] = ?       [latex] \frac{1}{2} [/latex]      [latex] \frac{2}{3} (x) - \frac{1}{2} [/latex] = ?       [latex] \frac{2}{3} [/latex]     L denominator = 3     R denominator = 2    Put them together it would be 6     [latex] \frac{4(x) - 3}{6 } [/latex] = ?     4(x) - 3 = ?    Let's add 3 from your sides   Repeat the process but let's divide by 4    4(x) = 3   Answer   x = [latex] \frac{3}{4} [/latex] 3. 3(x) - 2(x) + 4 - [latex] \frac{15}{3} [/latex] = ?     [latex] \frac{5}{1} [/latex]    x + 4 - 5 = ?    x - 1  = 0  Now, let add the number 1 from each sides    Answer: x = 1  4.  4(x) + 7 - 2(x) +  17 = ?      2(x - 5)     2 = ?     x - 5 = 0    Replace the subtraction symbol and make it a addition symbol ( but by 5)   Answer: x = 5  5.    .5(x) - 10 = ?         [latex] \frac{1}{2} [/latex]        [latex] \frac{1}{2} (x) - 10[/latex] = ?        [latex] \frac{10(2) }{2} [/latex]        [latex] \frac{x - 20}{2} [/latex]         x - 20 =  0  Add the number 20 to each of your sides after replacing the subtraction symbol to a addition symbol      Answer: x = 20
