Question

solving a system of linear equations using substitution solve this system of equations using substitution: y = 2x - 4 x + 2y = 10 step 1: substitute for y in the second equation which is the resulting equation? x + 2(2x - 4) = 10 step 2: which is the next step to solve for x? distribute 2 step 3: which terms can be combined to isolate the variable term the left side? x and 4x step 4: which step isolates the variable term on the left side? subtract 5 add 5 divide by 5

Explanation:

Step1: Review current equation

We have $5x - 8 = 10$ after combining like terms.

Step2: Isolate variable term

To isolate $5x$ (the variable term) on the left, we need to eliminate $-8$. We do this by adding 8 to both sides of the equation.
<Expression>
$5x - 8 + 8 = 10 + 8$
</Expression>

Answer:

Add 8
