-x - 2 + 15x = 14x - 2 = 2(7x - 1)
OK, SO 15x-3 = 2x+1 15x - 3 + 3 = 2x + 1 + 3 (add three to each side) 15x=2x+4 (simplIfy) 15x-2x=2x-2x+4 (subtract 2x from each side) 13x=4 (simplify) (13x/13)=(4/13) (divide each side by 13) x≈0.30769231
If y equals 3, 7 - 5y would be:7 - 5(3)Simplify.7 - 15 = -8.In conclusion, 7 - 5y = -8.
22 + y
Add like terms together: 21x-21
15x-20y= 7 5y-3 +10x
5(3x + 2 + y)
6y
-x - 2 + 15x = 14x - 2 = 2(7x - 1)
27
6 - y + 5y - 6y = 6 - 2y
27x - 5y
7
OK, SO 15x-3 = 2x+1 15x - 3 + 3 = 2x + 1 + 3 (add three to each side) 15x=2x+4 (simplIfy) 15x-2x=2x-2x+4 (subtract 2x from each side) 13x=4 (simplify) (13x/13)=(4/13) (divide each side by 13) x≈0.30769231
divide numerator and denominator by 3x: 4/5
-10
5y = 15x -45 Divide by 5 y = 15x/5 -45/5 y = 3x -9 y = mx + b m= 3 6 = -9 The slope is 3 The y intercept is -9
