5x+49 = 8x+13 49-13 = 8x-5x 36 = 3x x = 12

8x-4 = -7+5x 8x-5x = -7+4 3x = -3 x = -1

3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)

5x+1+x-2 = 8x+6 5x+x-8x = 6+2-1 -2x = 7 x = -3.5

first get the left hand side to only contain x's this requires you to get rid of the 9 on the left hand side so minus 9 on both sides of the equal sign so 8x + 5x + 9 = 61 becomes 8x + 5x +9 -9 = 61 -9 which is 8x + 5x = 52 now add the x's so 13x = 52 then divide both sides by 13 to find the value of x x = 4

8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33

7+8x-5 = 8x+7-5x Subtract 7 from both sides: 8x-5 = 8x-5x Subtract 8x from both sides: -5 = -5x Divide both sides by -5: x = 1 So the equation implies x = 1
