Q. 0.5(8w+2v)=38w=2−v+4wWhich of the following accurately describes all solutions to the system of equations shown?Choose 1 answer:(A) v=1 and w=41(B) v=4 and w=−41(C) There are infinite solutions to the system.(D) There are no solutions to the system.
Simplify Equation 1: Simplify the first equation.Given the equation 0.5(8w+2v)=3, distribute the 0.5 to both terms inside the parentheses.0.5×8w+0.5×2v=34w+v=3
Simplify Equation 2: Simplify the second equation.Given the equation 8w=2−v+4w, subtract 4w from both sides to isolate the terms with w on one side.8w−4w=2−v4w=2−v
Compare Simplified Equations: Compare the two simplified equations.We have 4w+v=3 from Step 1 and 4w=2−v from Step 2. Notice that both equations have 4w as a term. We can set them equal to each other to find the relationship between v and w.4w+v=4w−v+2
Solve for v: Solve for v.Subtract 4w from both sides of the equation.v=−v+2Add v to both sides to get all v terms on one side.2v=2Divide both sides by 2 to solve for v.v=1
Substitute and Solve for w: Substitute v=1 into one of the simplified equations to solve for w. Using the equation from Step 1: 4w+v=3, substitute v=1. 4w+1=3 Subtract 1 from both sides. 4w=2 Divide both sides by 4. w=0.5
