Write as a Vector Equality -4x+2y=-10 , y=2x-5
Problem
Solution
Rearrange the equations into standard form
a*x+b*y=c The first equation is already−4*x+2*y=−10 For the second equation, subtract2*x from both sides to get−2*x+y=−5 Identify the coefficients of the variables
x andy to form the column vectors. The coefficients forx are−4 and−2 The coefficients fory are2 and1 Express the system as a linear combination of these column vectors. Multiply the
x coefficient vector byx and they coefficient vector byy Set the sum of these vectors equal to the vector of constants from the right-hand side of the equations, which are
−10 and−5
