x = 27/5
Step-by-step explanation:
5x - 1 = 26
Add 1 to each side
5x - 1 = 26

5x/5 = 27/5
x = 27/5

Answer:
216 in²
Step-by-step explanation:
a = bh
a = 18 * 12
a = 216
X= -4y let this be equation 1
x+5y=2 let this be equation 2
substitute equation 1 in 2
-4y + 5y = 2
y=2
substitute the value of y in equation 1
x= -4y
x= -4(2)
x= -8
