Your friend says that any system of equations that can be solved by elimination can be solved by substitution in an equal or fewer number of steps. Order the steps for solving the system by each method to determine if your friend is correct. Only solve for one variable. The steps after solving for one variable are the same.
Equation 1: 8x-5y=11
Equation 2: 4x-3y=5
Name all 6 steps in order to solve each, as well as the eliminations.
Is your friend correct?
(YES OR NO) ___the system above can be solved in fewer steps by
than by (SUBSTITUTION OR ELIMINATION) than by (SUBSTITUTION OR ELIMINATION).

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
