Subtract 3x from both sides then isolate the variable. Sooooo... 5x+7=3x-5 2x+7=-5 2x=-12 x=-6

5x + 7 = 3x - 5 First, subtract 3x from both sides. [latex]5x = 7 - 3x = -5[/latex] Second, keep the 7 and subtract the 5x - 3x to get 2x. [latex]2x + 7 = -5[/latex] Third, subtract the 7 from both sides. [latex]2x = -5 - 7[/latex] Fourth, simplify -5 - 7. [latex]2x = -12[/latex] Fifth, take the 2 and divide it on both sides, leaving just x in its place. [latex]x = -\frac{12}{2} [/latex] Sixth, since 6 goes into 2 to get 12, simplify the fraction to 6. [latex]x = -6[/latex] Answer: x = -6
