what is the best first step for solving the given system using substitution while avoiding fractions?
2x+6y=7
6x+18y=24
solve for x in the first equation.
solve for y in the first equation.
solve for x in the second equation.
solve for y in the second equation.

Solve for x in the second equation.

Step-by-step explanation:

To solve a system of equations by substition you have to solve one of the equations for X or Y and then substitute that value on the X of the other equation, if you want to avoid fractions, you can use the x of the secon equation, like this:

So by solving X for the second equation you avoided fractions when substituting the value for X on the first equation.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
