Algebra Difficulty 1.8 Junior Find the answer
If y=1 and 4x−2y+3=3x+3y, what is the value of x?
A number or a short expression. Spacing and $ signs are ignored.
Solution
Substituting y=1 into the second equation, we obtain 4x−2(1)+3=3x+3(1). Simplifying, we obtain 4x−2+3=3x+3 or 4x+1=3x+3. Therefore, 4x−3x=3−1 or x=2.
