Answer:
x = 9 and y = -7
Step-by-step explanation:
given:
using substitution method:
2(-4y - 19) + 2y = 4
-8y - 38 + 2y = 4
-6y = 42
y = -7
Solve for x:
x = -4(-7) - 19
x = 28 - 19
x = 9
Answer:
X = 0.6
Step-by-step explanation:
5/2X + 2 = 3.5
subtract 2 from each side
5/2X = 1.5
change 5/2X to 2.5X
2.5X = 1.5
divide both side by 2.5
X = 1.5/2.5
X = 0.6
C. Multiply both sides by 9/5.
C = 5/9(F – 32)
We want to isolate F, which means we need to get F alone.
The quantity in the parentheses is multiplied by 5/9. We need to do the opposite, or multiply by the reciprocal to isolate the parentheses
9/5 C = 9/5* 5/9(F – 32)
9/5 C = F-32
This is the first step in isolating, or solving, for F
