Solve for x: 2 over 5 plus 3 over 5 x equals quantity x plus 5 over 10.

x = -3

x = 2

x = -3 and x = 2

no solution

x=-1/4

Step-by-step explanation:

2/5+3/5x=x+5/10

subtract 2/5 form both sides

3/5x=x+1/10

subtract x form both sides

-2/5x=1/10

Multiply both sides by 5

-2x=1/2

x= - 1/4

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
