Answer:
x=0, y=-12
Step-by-step explanation:
you can use substitution to solve for x
-3(x-12)=2x+36
-3x+36=2x+36
subtract 36 from both sides and add 3x to both sides
0=5x
x=0
now plug in 0 as x for either equation
y=0-12
y=-12
to check your work plug in x and y into the other equation
-3(-12)=2(0)+36
36=36

Step-by-step explanation:
Answer:
f(-10)=53
Step-by-step explanation:
Let
f(x)=
+5x+3.............(1)
we have to find
f(-10)=?
for this we will put x=-10 in equation (1)
f(-10)=
+5(-10)+3
f(-10)=100-50+3
f(-10)=53
