Answer: x=2 and y=−1
Step-by-step explanation:
5x+7y=3for x:
5x+7y=3
5x+7y+−7y=3+−7y(Add -7y to both sides)
5x=−7y+3
x= −7/ 5 y+ 3 /5
Substitute −7 /5 y+ 3 /5 for x in2x+3y=1:
2( −7/ 5 y+ 3 /5 )+3y=1
1 /5 y+ 6 /5 =1(Simplify both sides of the equation)
1 /5 y= −1 /5
y=1
Substitute −1 for y in x
−7 /5 y+ 3 /5 : x=
x=2
x=2(Simplify both sides of the equation)
Answer:
elmo is 3 right now
5x -4 = 3x+2
2x= 6
