Q. Is (1,8) a solution to this system of equations?y=4x+4y=6x+2Choices:(A)yes(B)no
Substitute and Verify: First, we will substitute the point (1,8) into the first equation and check if it holds true. The first equation is y=4x+4. If we substitute x=1 and y=8, we get 8=4×1+4.
Check First Equation: After performing the calculation, we find that 8=4+4, which is true. Therefore, the point (1,8) satisfies the first equation.
Check Second Equation: Next, we will substitute the point (1,8) into the second equation and check if it holds true. The second equation is y=6x+2. If we substitute x=1 and y=8, we get 8=6×1+2.
Verify Second Equation: After performing the calculation, we find that 8=6+2, which is also true. Therefore, the point (1,8) satisfies the second equation as well.
Solution Confirmation: Since the point (1,8) satisfies both equations, it is a solution to the system of equations.
