- Q1what is the first step in the substitution method?substitute in the value of the isolated variable into the other equationisolate one of the variables in one of the equationsStep 230sM8AL-Ih-3
- Q2solve by substitution: y=3x+14 y=-4xy=3y=4y=2y=130sM8AL-Ih-3
- Q3What is the first step in solving systems of linear equation by elimination?add or subtract the equations to eliminate one of the variablesstep 3multiply, if necessary, one or both equations by a constant so at least one pair of like terms has the same or opposite coefficients30sM8AL-Ih-3
- Q4solve by elimination: x+2y=13 -x+y=5(1,6)(2,5)(0,0)30sM8AL-Ih-3
