Answer:
Estimate (eye-ballin'): around (3, 3)
Calculation: (2.6, 3.2)
Step-by-step explanation:
<u>Given:</u>
4x + 3y = 20
y = 2x - 2
<u>Sophia's strat is absolutely correct. She makes two equations into one. This is called "substitution":</u>
- Insert <em>y</em> of 2nd equation as <em>y</em> in 1st equation:
4x + 3(2x - 2) = 20
<em>**Remember to multiply the entire thing by 3**</em>
4x + 6x - 6 = 20
<em>**Solve for x**</em>
10x - 6 = 20
10x = 26
x = 2.6
<u>Now that we have </u><u><em>x</em></u><u>, just plug it into any equation to find </u><em><u>y </u></em><u>(hint 2nd is easier):</u>
y = 2(2.6) - 2
y = 3.2
