Luis solves the following system of equations by elimination. 5s+3t=30 2s+3t=-3 what is the value of s?

we have

> equation a

> equation b

solve the system of linear equations by elimination

multiply the equation b by

> equation c

adds equation a and equation c

therefore

the answer is

the value of s is
