So, to find if X = 4 for both equations provided, we need to substitute the Xs in the equations and see if they balance out.
For the first equation,
3x+10-(5+3)=14
Every time we see an X, we need to place a 4 in its place.
3(4)+10-(5+3)=14
Using the order of operations, PEMDAS, we start to solve the equation.
3(4)+10-(5+3)=14
12 + 10 - (5+3) = 14
12 + 10 - (8) = 14
12 + 10 - 8 = 14
22 - 8 = 14
14 = 14
TRUE.
For the first equation, x does indeed equal 4.
However, we still need to see if x equals 4 for BOTH of the equations.
3x+10(3x-2)=60
3(4) + 10(3(4)-2) = 60
12 + 100 = 60
112 = 60
This isn't true.
To conclude, the answer is false. X doesn't equal 4 for both of the equations provided.
Hope I could help you out!
