Answer:
(3, -7) and (1, 2) are solutions to the equation
Step-by-step explanation:
Simply replace the (x, y ) pair of values in the equation and see if the equality holds:
Pair (0, -8) :
9 (0) + 2 (-8) = -16 therefore this pair is NOT a solution of the equation
Pair (3, -7):
9 (3) + 2 (-7) = 27-14 = 13 therefore this pair IS a solution of the equation
Pair (1, 2):
9 (1) + 2 (2) = 9 + 4 = 13 therefore this pair IS a solution of the equation
Pair (4, -5):
9 (4) + 2 (-5) = 36 - 10 - 26 therefore this pair is NOT a solution of the equation
Answer: 43/19
Step-by-step explanation:
4x−2+3(5x−2+7)=56
Step 1: Simplify both sides of the equation.
4x−2+3(5x−2+7)=56
4x+−2+(3)(5x)+(3)(−2)+(3)(7)=56(Distribute)
4x+−2+15x+−6+21=56
(4x+15x)+(−2+−6+21)=56(Combine Like Terms)
19x+13=56
19x+13=56
Step 2: Subtract 13 from both sides.
19x+13−13=56−13
19x=43
Step 3: Divide both sides by 19.
19/19x=43/19 thus the answer is 43/19
