Answer:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 5y = 15x - 4
[2] y = 3x - 4/5
// Plug this in for variable y in equation [1]
[1] 15x - 20•(3x-4/5) = 7
[1] -45x = -9
// Solve equation [1] for the variable x
[1] 45x = 9
[1] x = 1/5
// By now we know this much :
x = 1/5
y = 3x-4/5
// Use the x value to solve for y
y = 3(1/5)-4/5 = -1/5
Solution :
{x,y} = {1/5,-1/5}
Answer:

Step-by-step explanation:
Answer:
Step-by-step explanation:
The given equation is
-3(h+5)+2=4(h+6)-9
We expand to obtain;
-3h-15+2=4h+24-9
Group similar terms;
-3h-4h=24-9+15
Combine the similar terms;
-7h=30
Divide both sides by -7
