This can be displayed as a system of equations.
x = 3 + 5y
x - y = 11
Because we have a value of x we can plug it into the value of x in the second equation.
(3 + 5y) - y = 11
3 + 5y - y = 11
Combine like terms.
3 + 4y = 11
Subtract 3 from both sides.
4y = 8
Divide both sides by 4.
y = 2
Now that we have a constant value for y, we can replace the value of y in the second equation with 2 to solve for x.
x - 2 = 11
Add 2 to both sides.
x = 13
Now, let's verify.
13 = 3 + 5(2)
13 = 3 + 10
13 = 13 √ this is correct.
13 - 2 = 11
11 = 11 √ this is correct.
The first number, or x, is equal to 13.
The second number, or y, is equal to 2.
Answer:
S.A=132
Step-by-step explanation:
A=[ x b x h]2
A= x 4 x 3 x 2 12+50+40+30=132
A=12 cm²
A=L x W
A=10 x 5=50
A=L X W
A=10 X 4=40
A=L X W
A=10 X 3=30
Answer:
1.Solve for y in 2x+y=-3
y=-3-2x
2. Substitute y= -3 - 2x into 4x-2y=10
8x+6=10
3 Solve for x in 8x+6=10
x=1/2
4. Substitute x=1/2 into y = - 3 - 2x
y= -4
5. So you get...,
x=1/2
y=−4
