Solve each equation.

x+42y=912

Short Answer

Expert verified

The solution is 5,6.

Step by step solution

01

– Description of step.

As the matrices are equal, the corresponding elements are equal. Write the two linear equations to show this equality.

x+4=92y=12

02

– Description of step.

Divide each side of 2y=12by 2 to find the value of y.

2y2=122y=6

03

– Description of step.

Subtract 4 from both the sides of x+4=9 and simplify to find the value of x.

x+4鈭�4=9鈭�4x=5

Therefore, the solution is 5,6.
