Answer:
x = - 2 , y = 2
( - 2, 2)
Step-by-step explanation:
first equation add 1/2 to both sides
second equation subtract 2x from both sides
Solve the first equation
subtract x/2 from both sides
substitute for y in the other equation
add
to 2x
subtract 1 from both sides
divide both sides by
x = - 2
substitute the value of x into an equation
distribute
y = 1 + 1
y = 2
x = -2, y = 2
( - 2, 2)
Answer:
Step-by-step explanation:
15x - 10 = 20
15x = 20 + 10
15x = 30 (divide both sides by 15 to get x)
15x/15 = 30/15
x = 2
