Question

(iii) Solve the simultaneous equations 2x + y = 8; y = 1+x 2 국 graphically​

Answer 1

Solve $2x+y=8$ and $y=1+2x$ graphically

Definition:

The graph of a linear equation in two variables is a line.If we know an equation is linear,then we can graph it by finding the solutions.

Step-by-step explanation:

The attachment shows the graph of $2x+y=8$ and $y=1+2x$,and the point of intersection is (1.75,4.5) which is a solution for these equations.

Therefore,the value of x is 1.75 and y is 4.5
