The answer is 117/8 and that is simplified decimal form is. 14.625
First the left fraction 3 x 8=24+3=27 so it is 27/8
Then the right 4 x 3=12+1=13
27 x 13=351
8 x 3=24
351/24
Three main methods come to mind: Substitution method, Elimination method, Matrix row-reduction.The first two methods are taught in early grades in most high schools. Matrix row-reduction is taught in senior years in high school, or more likely, in the early years of a university math or science program.

Step-by-step explanation:
Substitution is a method to solve a system of equations by substituting an expression from one equation into the other.
To begin, first solve one equation by isolating for one variable. Choose the equation which will have the least number of steps to do so.
y + x = 3 can be solve for x or y by subtracting the other variable. Since this only requires one step use this equation. Either variable can be used.
