Combining like terms, 16x + 20 = 180
or 16x = 160 so that x = 10
x+10+3x+14=1804x+24=1804x=180-244x=156x=156\4x=39
Ok so 2x + 3x + 2x + 3x = 180.... so combine like terms, 2x + 3x + 2x + 3x is 10x, because 2+3+2+3 is equal to 10, and then so 10x = 180, so divide each side by 10 because the "10" on the left side is multiplying the x, and we want "x" by itself and the opposite of multiplication is division, and 10x/10 is x and 180/10 is 18, so x = 18.
(2, -1)
x=10
3x + 2 = -10 3x = -12 x = -4
-2
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
3+3x+7x=13 3x+7x=10 10x=10 x=1
x = 2
The answer is -7
(4, -1)
x=-3
