5x - 3 + 2x + 7 = ?7x + 5 = ?
5x + 2x + 6 = 48 7x + 6 = 48 ....Because you simplify 5x + 2x 7x = 42 ....Because you subtract 6 from both sides to help isolate x x = 6 ....Because you divide both sides by 7 to isolate the x.
5x + 2x - 7 = 0 Simplify 7x - 7 = 0 Add 7 to both sides 7x - 7 + 7 = 0 + 7 7x = 7 divide both sides by 7 x=1
3x + 17 + 5x = 7x + 10Combine (add) the 'x'-terms on the left side of the equation:8x + 17 = 7x + 10Subtract 17 from each side:8x = 7x - 7Subtract 7x from each side:x = -7
i will simplify: 5 times x times 6= 7 times x - 16
