-2x+14=20 -2x=20-14 -2x=6 -2x/-2=6/-2 x=-3
88+x=3x+22 88=2x+22 66=2x x=33
if 2x+3=9 then 2x=6 so x=3
the converse of this conditional is true
Then x = 6 Therefore; 5x + 3 = 33 First you have to solve the value of X: 8X + 5X + 2X +4X = 114; OR 19x = 114. When you divide both sides of the equation by 19 to solve for X, you find that X = 6. Ergo, 5X + 3 = 30 + 3 = 33; hence, 5X + 3 = 33.
3
2x+3 = 7 2x = 7-3 2x = 4 x = 2
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
2x+3 = -11 2x = -11-3 2x = -14 x = -7
x = 3 and y = 3 Form a simultaneous equation and solve by elimination.
3x+4 = 2x-3 3x-2x = -3-4 x = -7
(3,3)
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
3x-2 = 2x+3 3x-2x = 3+2 x = 5
2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
