Determine the solution to each linear system by using the substitution method.
show

a. 2x+3y=34
y=5x

b. y=4x+2
y=3x-2

c. 3x+2y=4
2x-y=5

d. 3x+y=8
6x+2y=10

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
