6.3+practice+problems

**-2x + 2y = 10 2x + 10y = -18** Step one - Elimate one of the variable, by creating opposite coefficients which will cause it to be equal to 0 when you cross it out, so clear it off Now the problem should look like this- 2y = 10 10y = -18 Step two - Add/subtract both sides 8y = -8 The answer is y = -1 Step three - Substitute in they y value into the one of the original equations to solve for the other variable 2x + 10(-1) = -18 Which after solving looks like this, 2x + -10 = -18 Next distribute the numbers with no variables 2x = 8 So your answer is X = 4
 * Solving 6.3 first problem- **

So your final answer (4,-1)
