2x+7y = 38 5x8y=38 the thing is to make the coefficient of one of the variables equal and then eliminate it. multiplying the first equation by 5, 10x+35y = 190 second equation by 2, 10x16y=76 adding them eliminates the xvariable 35y  16y = 190 + 76 Therefore, 19y = 114 find y from here, then substitute in any one of the originally given equations and get the values of x.
