Y=x+3

y=4x

solve each system of equations algebraically

(1,4)

Step-by-step explanation:

y=x+3

y=4x

Substitute the second equation into the first equation

4x = x+3

Subtract x from each side

4x-x = x-x+3

3x = 3

Divide each side by 3

3x/3 = 3/3

x = 1

Now we need to find y

y = 4x

y = 4*1

y=4

Y=x+3

Y=4x

4x=x+3

-x. - x

3x=3

~. ~

3. 3

X = 1

Y = (1) + 3=4

Y=4 (1) = 4
